Matrix configuration with Jenkins pipelines

Question

The Jenkins Pipeline plugin (aka Workflow) can be extended with other Multibranch plugins to build branches and pull requests automatically.

Answer 1

In order to test each commit on several platforms, I've used this base Jenkinsfile skeleton:

def test_platform(label, with_stages = false)
{
    node(label)
    {
        // Checkout
        if (with_stages) stage label + ' Checkout'
        ...

        // Build
        if (with_stages) stage label + ' Build'
        ...

        // Tests
        if (with_stages) stage label + ' Tests'
        ...
    }
}

/*
parallel ( failFast: false,
    Windows: { test_platform("Windows") },
    Linux:   { test_platform("Linux")   },
    Mac:     { test_platform("Mac")     },
)
*/

test_platform("Windows", true)
test_platform("Mac",     true)
test_platform("Linux",   true)

With this it's relatively easy to switch from a sequential to a parallel execution, each of them having their pros and cons:

• Parallel execution runs much faster, but it doesn't contain the stages labelling
• Sequential execution is much slower, but you get a detailed report thanks to stages, labelled as "Windows Checkout", "Windows Build", "Windows Tests", "Mac Checkout", etc.)

I'm using the sequential execution for the time being, until I find a better solution.
